Description
Verfahren zur Herstellung von Halbzeug aus faserverstärktem Verbundwerkstoff Die Erfindung betrifft ein Verfahren zur vorzugsweise kontinuierlichen Herstellung von Halbzeug aus einem faserverstärktem Verbundwerkstoff durch unter Wärmezufuhr erfolgendes Verformten, z. B. Walzen, Ziehen, Extrudieren eines losen Vormaterials, welches aus mit einem HAllmaterial bedampften, die Fasern bildenden Kernmaterial besteht. Process for the production of semi-finished products from fiber-reinforced composite material The invention relates to a method for preferably continuous production of semi-finished products made of a fiber-reinforced composite material by applying heat deforming taking place, e.g. B. rolling, drawing, extrusion of loose raw material, which is made of a core material which forms the fibers and is vapor-deposited with a HAllmaterial consists.
In der DOS 1.608.206 ist ein solches Verfahren beschrieben, bei welchem ein Kernmaterial bedampft wird, welches zuvor in die Form sehr dünner Fäden (Fasern) gebracht und auf Spulen bevorratet,wUrde, um für die Bedampfung von diesen Spulen bündel- oder-strangweise abgewickelt zu werden. Auch anderes, längsorientiertes Material, wie Whisker, werden als Kernmaterial vorgepchlagen. In dem Verbundmaterial, das durch Verformen und Verdichten des bedampfen Kernmaterials erzeugt wird, liegt dieses in Forn längsorientierter Fasern vor, welche voneinander durch das aufgedampfte ilüllinaterial isoliert sind, während die Schichten des Hüllmaterials innig miteinander verbunden sind'.Such a method is described in DOS 1.608.206, in which a core material is steamed, which is previously in the form of very thin threads (fibers) brought and stored on reels, in order for the steaming of these coils to be unwound in bundles or strands. Also other, longitudinally oriented Material such as whiskers are suggested as core material. In the composite material, which is generated by deforming and compressing the vapor-deposited core material this in the form of longitudinally oriented fibers, which are separated from each other by the vapor-deposited ilüllinaterial are isolated, while the layers of the envelope material are intimate with one another are connected'.
Dieser Verbundwerkstoff zeichnet sich durch eine außergewöhnlich hohe Festigkeit aus.This composite material is characterized by an exceptionally high Strength.
Qer^Iacateil des beschriebenen Herstellungsverfahrens liegt in seinen sehr hohen Kosten, welche vor allen darauf beruhen, daß das Kernmaterial vor der Bedampfung in Faser- oder lMisKerform gebracht wird. Dieser Prozeß ist umständlich, disko-ntinuierlish und teuer-Denn Fasern mit einem Durchmesser in der Größenordnung von 18 bis 1 my werden z.B. aus flüssigen Schmelzen von Gläsern, Quarzen und Silikaten gezogen, während die Herstellung von Whiskern - z.B. aus Kohlenstoff, Metallen, Bor, Borkarbid, Beryllium, Siliziumkarbid - durch elektrolytisches Abscheiden aus einem Salz, durch Kondensation aus einem Dampf, Reduktion von Salzen oder Ausfällen aus einer Lösung erfolgt.Qer ^ Iacate part of the manufacturing process described lies in his very high costs, which are based on the fact that the core material before the Steaming is brought into fiber or lMisKerform. This process is cumbersome Discontinuous and expensive - because fibers with a diameter on the order of magnitude from 18 to 1 my are e.g. from liquid melts of glasses, quartz and silicates drawn, while the production of whiskers - e.g. from carbon, metals, Boron, boron carbide, beryllium, silicon carbide - by electrolytic deposition a salt, by condensation from a vapor, reduction of salts or precipitation takes place from a solution.
Die hone Festigkeit dieser Verbundwerkstoffe, die fast bis zur Erweichungstemperatur des Kernmaterials erhalten bleibt, beruht auf den geringen Durchmessern des Kernmaterials, die unter 10 my liegen und bei der Gröβenordnung von 1 my eine Festigkeit zur Folge haben, welche sich der theoretischen, durch die atomare Kohäsion begründeten Festigkeit nähert.The hone strength of these composites almost up to the softening temperature of the core material is retained, is due to the small diameters of the core material, which are less than 10 my and a strength of around 1 my Have consequences which are based on the theoretical, by the atomic cohesion Strength is approaching.
Aufgabe der Erfindung ist es, die hohen Kosten der Faserherstellung zu vermindern. Dies geschieht erfindungsgem4 dadurch, daß als Kernmaterial unbehandeltes oder durch Zerkleinerung aufbereitetes Pulver bedampft, bis zum Erweichungspunkt des Kernmaterials erwärmt und die Verformung dera geleitet wird, daß das Kernmateriald zu längsorientierten Fasern verformt wird.The object of the invention is to reduce the high cost of fiber production to diminish. According to the invention, this takes place in that the core material is untreated or powder prepared by crushing, steamed to the softening point of the core material is heated and the deformation is conducted so that the core materiald is deformed into longitudinally oriented fibers.
Eine solche Verformung findet überall dort statt, wo erhebliche Drücke in Querrichtung auf das Material ausgeübt werten, also beispielsweise beim Hämmern, Ziehen, Walzen, Extrudieren. Dabei paßt sich das aufgedampfte Hüllmaterial der Verformung der Pulverpartikel zu sehr dünnen, längsorientierten Fasern an und bildet weiterhin eine geschlossene Hülle, welche die eingeschlossene Faser von den benachbarten isoliert.Such a deformation takes place wherever there is considerable pressure evaluate in the transverse direction on the material, e.g. when hammering, Drawing, rolling, extruding. The vapor-deposited envelope material adapts to the deformation the powder particles into very thin, longitudinally oriented fibers and continue to form a closed sheath which isolates the enclosed fiber from the neighboring ones.
Die mechanische Verformung der Kernmaterial-Partikel nach dem Bedampfen ist offensichtlich sehr viel einfacher und billiger als die oben beschriebene Herstellung von Fasern oder tihiskern au-s dem Kernmaterial vor dem Bedampfen.The mechanical deformation of the core material particles after vapor deposition is obviously much simpler and cheaper than the production described above of fibers or thistle core from the core material before steaming.
Besteht die Gefahr, daß Büllw und Kernmaterial ineinander löslich-sind, so kann vor der Bedampfung des Kernmaterials mit dem Hüllmåterial eine Diffusionssperre oder Reaktionsbarriere aus anderem geeigneten material aufgedampft werden.If there is a risk that bulb and core material are soluble in one another, a diffusion barrier can be used before the core material is vaporized with the shell material or a reaction barrier made of other suitable material can be applied by vapor deposition.
Bei einer bevorzugten Ausführungsform des Verfahrens wird das lose Vormaterial vor der Verformung zu einem Block verpreeßt und gesintert, der dann seinerseits der Verformung unterworfen wird.In a preferred embodiment of the method, this becomes loose Pre-material is pressed and sintered into a block before deformation, which is then in turn is subjected to deformation.
Zweckmäßig wird ein Hullmaterial verwendet, dessen Schmelzpunkt oberhalb des Erweichungspunktes des Kernmaterials liegt. Gute Ergebnisse werden mit einer Kombination von Titan als Hüllmaterial und SiO2 als Kernmaterial erzielt, für welche eine Ver--formungstemperatur zwischen 15850C (Erweichungspunkt von Si02) und 16680C (Schmelzpunkt von Titan2 erforderlich ist. Auch die Kombination von TANTAL mit Tonerde Al 203 ist vorteilhaft. Dieses Material wird unterhalb 29960C (Schmelzpunkt von Tantal) gepreßt und gesintert und anschließend bei einer Temperatur zwischen 18000C (Erweichungspunkt von Al203) und 29960C verformt.A sheath material is expediently used, the melting point of which is above the softening point of the core material. Good results will come with a Combination of titanium as the shell material and SiO2 as the core material achieved for which a deformation temperature between 15850C (softening point of Si02) and 16680C (Melting point of Titan2 is required. Also the combination of TANTALUM with alumina Al 203 is advantageous. This material is below 29960C (melting point of Tantalum) pressed and sintered and then at a temperature between 18000C (Softening point of Al203) and 29960C deformed.
